SWITCH-OPERATING MECHANISM.

Application filed December 1923. Serial No. 678,351.

This invention relates to switches and has for its object a particularlysimple and eflicient operating mechanism for switches lo cated in boxes,which mechanism is movable parallel to the plane of the cover or theopen side of the box and is detachable upon removal ofthe cover andattachable upon the placing of the cover on the box.

The invention consists in the novel fea- 1 tures arid in thecombinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a longitudinal, sectional view I partly in elevation of aswitch and box provided with this operating, means.

Figure 2 is a fragmentary plan View of the box.

Figure 3 is a fragmentary detail view of the switch.

1 designates a box which may be of any suitable form, size andconstruction, the box being open at one side and having means asinternally threaded nipples 2 for connection to conduits which enclosethe service wires.

3 is a cover for theopen side of the box, the cover being detachablysecured in any suitable manner as by screws 1 extending through themargin of the cover and threading into the lugs 5 in the box near theopen side thereof.

6 designates the .switch, as a whole, the switch being mounted on a baseof insulation 7 suitably mounted in the box on the side thereof oppositethe cover. This switch may be of any suitable form, size andconstruction and the construction thereof forms no part of thisinvention.

Generally the switch includes a movable switch arm 8 pivoted at 9between its ends to a frame 10 mounted on the insulating base 7, theends of the arms being movable'into and. out of engagement with contacts11, 12 mounted on the base and connected to service wires. The arm 8 isactuated to have a snap or' quick make and break action by an actuatingpart 13 extending toward the open side of the box or the cover 3, thispart 13 being here shown as a lever pivoted. at 14 to the frame 10 andhaving anarm 15 connected to a carrier or rod 16 for a spring 17arranged to shift from either side to the other of the axis 9 of theswitch arm 8 in order that the spring may rock the switch after the partor lever 13 has been actuated far enough to shift the spring 17 to suchposition that the direction of its force on the yoke 18, which throwsthe switch arm 8, is reversed.

As the construction and operation of various forms of quick breakswitches are well known, further description is thought to beunnecessary and the switch mechanism, in so far as this invention. isconcerned, is pertinent only in, so far as it includes an operatmg partextending toward the cover.

The operating mechanism for said lever or part 13 comprises a rod orslide 19 movable in the cover and connected to the arm 13, the rod orslide 19 being movable in a direction parallel to the plane of the openside of the box or cover. Preferably the cover is formed with a domeportion 21 and the rod or slide 19 extends through a guide opening in aside wall 22 of the dome portion, and has a handle or knob 23 at itsouter end and means at its inner. end for engaging the actuating part orlever 13. The rod, as here illustrated, has a fork 24, which receivesthe end of the lever 13. The handle or knob 23 moves over the outer faceof the cover within the limits or outline of the cover.

Owing to the fork, the operating part disengages from the part 13, whenthe cover 3 is removed, and also engages said part when the cover 3 isplaced on the box. The rod 13 is also shown as formed witha head 25,which engages the inner faces of the walls of the dome 21 and holds therod from turning, the fork 24 before referred to is here shown ascarried by this head 25. The knob or handle 23 moves over the cover onthe outside of the dome portion 21 and hence does not project beyond theoutlines of the g5 ox or cover, so that, being arranged within theoutlines of the box or cover and movable in a direction parallel to theplane of the cover, it is protected against unintentional operation.

What I claim is:

1. The combination with a box open at one side, and a switch located inthe box'and having actuating part extending toward the open side, of acover for the open side havm5 ing a dome-shaped portion and an operatingmember slidable .through a side wall of the dome-shaped portion in adirection parallel to the plane of the open side of the box and beingconnected to the actuating part, the" 110 operating member having a headmovable between the inner faces of the side walls of the dome-shapedportion. I 2. The combination with a box open at one 5 side, and aswitch located in the box and having an actuating part extending towardthe open side, of a cover for the open side having a dome-shapedportion, and an operating member slidable through the side wall 10 ofthe dome-shaped portioh in a direction parallel to the plane of the openside of the box and being connected to the actuating part, the operatingmember having a head movable between the inner .faces of the side wallsof the dome-shaped portion, and also 15 having a fork receiving saidactuating part.

In testimony whereof. I have hereunto signed my name, at Syracuse, inthe county of Onondaga, and State of New York, this 15th day ofNovember, 1923.

RAYMOND H. OLLEY.
